REGISTER FOR PAPER-BOX MACHINES, 84.0.

SPECIPICATIONforming part of Letters Patent No. 375,781, dated January3,1888.

Application filed August 5, 1867.

To all whom it may concern: 7

Be it known that I, ELBERT L. STEELE, of Nashua, in the county ofHillsborough, State of New Hampshire, have invented a certain new anduseful Improvement in Registers for Paper-Box Machines, of which thefollowing is a description sufficiently full, clear, and exact to enableany person skilled inthe art or science to which said inventionappertains to lO make and'use the same, reference being bad to theaccompanying drawings, forming part of this specification, in which-Figure 1 is'afront elevation of my improved register detached; Fig. 2,an end elevation of the same, and Fig. 3 a front elevation of theregister attached to the cutter-wheel bar of a scoring-machine.

Like letters of reference indicate corresponding parts in the differentfigures of the draw- ZO'IDgS.

My invention relates to means for automatically registering the numberof sheets of paper or board used in the manufacture of boxes as thesheets pass through the scoring and cutting machines.

Much waste of stock is frequently occasioned in box-factories by cuttingtoo great a number of strips to make the quantity of boxes desired of acertain size, and as it necessitates a loss oftimeto count the stripsthe number required for a certain quantity 'of boxes is usually roughlyestimated.

Myimprovernentis designed to obviate these and other objections; and tothat end I make use of means which will be readily understood by allconversant with such matters from the following explanation.

In the drawings, A represents the body of the register, B O theindicating dials, and D 0 the cutter-wheel bar of the scoring-machine.

The body A of the register consists of a rectangular metallic plate, tothe lower edge and near one end of which is secured a backwardlyprojecting clamping-bar, G, provided with a 5 slot, 0, of a shapesuitable to receive the lower edge of the cutter-wheel bar D, to whichit is secured by the set-screw a. The bar G has a laterally-proj ect-ingarm, 00, (see Figs. 1 and 3,)

provided at its outer end with a downwardly- 0 projecting tube, y,having a vertical slot, 2.

Serial No. 246,178. {No model.)

A rod, b, which is disposed within the tube y, has a wheel, m, (see Fig.2,)journaled in its lower end, and is provided with a shoulder, d, theupper portion of said rod being reduced to pass through an opening inthe arm 00 and scre'wthreaded to receive a nut,f, by which it can beadjusted in said tube. A coiled spring, is disposed around the upperportionof the rod 12, between the shoulder d and arm 00. A flatlongitudinally-arranged steel spring, H, is pivoted at i to the lowerend of a vertically-adjustable plate, 70, secured to the body A byset-screws h, the inner end of said spring resting on a stop, P, securedto said body. Adownwardly-projecting bar, K,provided with ahorizontally-arranged arm, m has its upper end pivoted at Z to thespring H, its arm passing through the slot 2: in the tube 1 and beingsecured to the rod b below the spring 9.

The dial B is a circular disk provided on its periphery with one hundredteeth, its face being marked into spaces to correspond with said teeth,and the spaces numbered from one to one hundred consecutively. The dialis cen- 7 trallyjournaled in a stub-shaft (not shown) which projectsfrom the face of the body A, in such a position that a spring-pawl, L,which is pivoted on the inner end of the spring H, will engage the teethof said disk. A triangular 8o metallic washer, r, and anindicating-hand, t, are disposed on said stub shaft and secured theretoby a screw, q, the ends of the'hand and corners of the washer being bentagainst the face of the dial (see Fig. 2) to produce sufficient frictionto prevent said dial from being accidentally revolved.

The dial 0 is circular, and is provided on its circumference with tenteeth equidistant from each other and numbered on the surface 0 ofthedial from one to ten consecutively. This dial is journaled on astub-shaft (not shown) on the body A, having an indicator or hand,

j, disposed thereon and secured by the screw 6, the position of the dial0 being such that 5 when revolved its teeth will pass under the edge ofthe dialB and engage a stud,T,secured to the inner face thereof, (seeFig. 1,) thereby causing the dial 0 to be revolved one point for eachcomplete revolution of the dial B. A ten gravitating retaining-pawl, J,is pivoted to the upper end of a plate, M, secured to the plate E, beingso arranged as to engage the teeth of the dial B and prevent it frombeing turned backward. The lower end of the plate M is extended downwardto form a stop, N, for the pawl L and prevent it from carrying forwardthe dial B more than one space at a time.

In the use of myimprovement the registeris attached to the cutter-wheelbar D of a scoring-machine by means of its clamp G and screw a in suchmanner that its wheel at rests on the feed bed or cylinder Q of themachine between two of the cutter-wheels w. As the paper-board or othermaterial used in constructing the boxes is fed to the wheels w it passesunder the wheel m, elevating said wheel and causing the bar K to beforced upward, thereby moving the spring H and turning the dial B onepoint from right to left by means of its pawl L, in a manner which willbe readily obvious without a more explicit description. The arm H is inthe form of a spring, in order to compensate for the differentthicknesses ofboard passed under the wheel and prevent the indicatorfrom being moved more than one notch at a time. It will readily be seenthat when the'dial B has made one complete revolution the'stud T willengage a tooth of the dial 0 and move said dial one space from left toright, thus registering the number of sheets in hundreds thathave passedunder the wheelm. The coiled spring 9 forces the wheel at down againstthe bed Q as soon as it has passed each sheetof paper or board. Thetension of said spring may be regulated by means of the nutf, or bymoving the adjustable plate 70, which will raise or lower the rod K andchange the pressure ofthe bar b against said spring.

It will be obvious that the stops P N prevent the pawl L from moving thedial B more than one tooth at a time.

I do not confine myself to the use of both the nutf and adjustable plate7; for regulating the tension on the spring as either may be used andthe other omitted; neither do I confine myself to the use of the pawl J,as it may be entirely omitted,ifpreferred; nor to using only two dials BC, as another dial may be attached to the plate E and operated by a studon the dial C, to register the tens of thousands, if desired; nor tousing the register with paper-box maehinery,as it is adapted for otheranalogous purposes.

Having thus explained my invention, what I claim is- 1. A register ofthe character describcd,comprising a body, A, provided with theclamping-bar G, having the arm a", the tube y, attached to said arm andhaving the slot 2, the sliding bar Z) in said tube, the wheel m,journaled at the lower end in said bar, the spring g,nutf, rod K,pivoted arm Hypawl L,stop I, dial B, and hand 15, substantially asdescribed.

2. In a device of the character described, the combination of the bodyA, the plate is, adjustably secured to said body, the spring I-I,pivoted to said plate and provided with the spring-pawl L, avertically-sliding bar, I), provided with a wheel at its lower end, asupport for said bar, a rod, K, pivoted to said spring and engaging saidbar,and a toothed dial actuated by said spring'pawl, substantially asdescribed.

3. In a device ofthe character described,the body A, having the stopsNI, the toothed dial B, journaled on said body and provided with thestud T, and the dial 0, in combination with the adjustable plate is,spring H, having the pawl L, clamp G, having the arm a: and slotted tube1 the bar b, disposed in said tube and provided with the wheel at,spring g, and nut f, and the rod K, secured to said bar and pivoted tothe spring H, substantially as described.
